LOL! Methinks they do. Would you agree that such slips are telling? Just circumstantial evidence, but still. There is a problem, it's much more difficult to get 100% accurate proofreading onscreen than on paper (you can probably find typos at JtF too). But that stray "Magnesol" in there is just sloppy, what else is sloppy? Something to add might be whether Magnesol really does give the same results. If it's time-saving that's the aim there are ways round that without becoming more dependent on anyone. I don't accept it gives better-quality results unless maybe you're starting with a poorly completed product, in which case the magnesol is just masking the problem (like mist-washing). You can easily get within the standard specs with well-made homebrew biodiesel plus a few hours spent stir-washing it. If you GC'd the result and compared it with a sample of the same batch of homebrew dry-washed with Magnesol, what would it show? Has anybody seen such results?
